Abstract	TA method to reconstruct squark and gluino signals through the decay chain g  -> q qbar -> chi2 qqbar -> l R l qqbar -> chi1 l+ l- qqbar is described. The sbottom is reconstructed exploiting the expected b-tagging performance of the CMS detector in the chain g  -> b bbar -> chi2 bbbar -> l R l bbbar -> chi1 l+ l- bbbar. The study is performed in three different mSUGRA scenarios. With favourable parameters, the mass peaks can be reconstructed with 10 fb-1 of integrated luminosity. The main source of error on the measurements of the signal masses arises from the chi1 mass uncertainty.
